A production-ready email campaign brief answers five things on a single page: what we are sending, to whom, why, with which assets, and who signs it off. Longer than a page and nobody reads it. Shorter than these eight fields and you spend the next three days answering questions over email.
The eight sections:
- Objective and KPI
- Audience and segment
- Offer and key message
- CTA and destination
- Mandatory assets and copy sources
- Legal and compliance notes
- Deadlines per stage
- Named approvers
Below, each field with what a good version looks like, and a bad one taken from real campaigns.
Why do most briefs generate 14 clarification emails?
Because they're written as a record of a conversation, not as an instruction to produce something.
The person writing the brief already knows the answers. The copywriter, the designer, and the person building the send do not.
Three fields that look filled in but aren't:
"Audience: our database." Which database? All 180,000 contacts, or the 42,000 with marketing consent? Do we exclude people who bought last week? Do we exclude the segment that got the same offer eleven days ago? That's four emails right there, and the answers usually arrive after the copy is written.
"Deadline: end of the month." End of the month is a send date. It says nothing about when copy is due, when design gets the copy, when internal QA happens, or how long the client has to review. Teams discover the real deadline was six days earlier when the client asks for a subject line change on the morning of the send.
"Client to approve." Which person at the client? The marketing manager who briefed you, or the legal contact who has never seen the campaign and will have opinions about the word "guaranteed"? Unnamed approvers are how a campaign gets held for two days over a claim nobody flagged.
Each of these looks like a completed field. Each one is a question in disguise.
What should the objective and KPI field say?
One business objective, one primary metric, one target number, one measurement window.
Good: Reactivate lapsed subscribers. Primary KPI: 4% click rate on send 1, measured 7 days post-send. Secondary: 120 orders attributed within 14 days. Now the copywriter knows the email has to earn a click, not a purchase, and the designer knows the hero needs one dominant button.
Bad: "Increase engagement." Engagement isn't a number. It also doesn't tell anyone what to optimize. A brief with this objective produces an email with four competing CTAs, because nobody could argue that any of them were wrong.
How specific does the audience and segment field need to be?
Specific enough that someone else could build the segment without asking you.
Good: Segment lapsed_90d: at least one purchase, no email open in 90 days, marketing consent active, country ES/FR. 42,310 contacts as of March 3. Exclusions: anyone who received winback_feb, anyone with an open support ticket. Include the size. Size changes creative decisions and it changes whether the campaign is worth the production hours.
Bad: "Our database." See above. Add "plus the usual exclusions" and you've moved the segment logic into someone's memory.
What goes in offer and key message?
The exact commercial terms, plus one sentence of the message, plus what we are deliberately not saying.
Good: Offer: 20% off full-price items, code SPRING20, valid March 10–17, minimum spend €40, excludes sale items and gift cards. Message: the collection they browsed is back, and there's a week to get it cheaper. Do not say "biggest sale of the year." That's reserved for June.
Bad: "Spring promo, big discount." The copywriter writes "up to 20% off." Legal catches it four days later because "up to" implies tiers that don't exist. Two rounds of revision on an email that was correct the first time, wrong in the brief.
What should the CTA and destination field contain?
The exact button text, the exact URL, the tracking parameters, and the date the destination goes live.
Good: CTA: "Shop the collection." Destination: /spring-collection?utm_source=email&utm_medium=crm&utm_campaign=spring25_reactivation. Page live from March 9, 09:00 CET, owner: web team. Fallback if delayed: category page /new-in.
Bad: "Link to the landing page." Which landing page? Does it exist yet? Who's building it? Roughly one campaign in five is held on the morning of the send because the destination page wasn't ready and nobody had named an owner for it.
Which assets and copy sources are mandatory?
Every asset the campaign needs, per channel, with the source of the copy and the person who owns it.
Good:
- Email 1: subject line (max 45 characters), preheader, hero image, three content blocks. Copy source:
spring25_copy.docx, tab "Email 1." Owner: Marta. - Email 2 (reminder, March 15): reuses hero, new subject line.
- SMS: 160 characters including the short link. Owner: Marta.
- WhatsApp template: needs Meta pre-approval, submit by March 4.
- Landing page: hero + product grid. Owner: web team.
Bad: "Use the assets in the Drive folder." The folder contains eleven files, three of which are from last year, and two have the same name with _final and _final_v2. Every person who touches the campaign will pick a different one.
What legal and compliance notes belong in the brief?
The constraints that apply to this specific campaign, not a link to the brand guidelines.
Good: Discount terms must appear in the footer verbatim. No "guaranteed delivery by" claims; use "typically 2–3 working days." Consent basis: opt-in, marketing_email flag. Unsubscribe in footer. Legal reviewer: Nadia Ortiz, needs 48 hours.
Bad: "Legal will review." Legal reviewing at the end is not a compliance note. It's a delay you scheduled without knowing it. If a claim needs substantiation, the copywriter should know before writing it, not after.
How should deadlines be written?
One date per stage, each with an owner. Not a single send date.
Good: Copy final March 4 · Design final March 6 · Internal QA March 7 · Client review window March 7–9 (48 hours) · Final approval March 9, 17:00 · Send March 10, 10:00 CET.
Bad: "Live end of month." Every stage silently inherits the same deadline, which means every stage is late simultaneously. If your team already tracks tasks in a project tool, mirror these stages there rather than keeping them only in the brief. We've written about the trade-offs of running campaign production in Asana or Monday.com separately.
That "Internal QA" slot deserves more than a name on the calendar. See our pre-send checklist for the ten checks that actually catch errors before send.
Who counts as a named approver?
A person, by name, with a decision deadline and a stated default if they don't respond.
Good: Copy approval: Marta Ruiz (internal). Compliance: Nadia Ortiz. Client sign-off: Javier Peña, Marketing Manager, required before send. If no response by March 9, 17:00, campaign moves to March 12. One accountable approver per stage. Consulted people are consulted; they don't hold the launch.
Bad: "Client to approve." Or worse, a distribution list. Five people on a thread means nobody has said yes, and when someone asks later who approved the 20% subject line, the answer is an email search.
For the full mechanics of that deadline (the response window, the escalation, what counts as approval), see our guide on how to set a client approval SLA.
How do you roll this out with clients and stakeholders?
Don't send the template around and hope.
Three things make it stick.
Fill the first two together. Book 30 minutes with the client or the stakeholder and complete the brief live, on a call. They'll see it takes less time than the clarification thread it replaces, and they'll notice which fields they couldn't answer. That's the argument, not the document.
Make it a gate, not a suggestion. No brief, no production slot. This is easier to hold if you've told them the reason: every unanswered field becomes a revision round later, and revision rounds are what push the send date. See how to cut campaign review rounds from four to one for how those rounds compound. Agencies usually put this in the SOW; in-house teams usually put it in the intake form.
Version it once, then freeze it. The brief is the thing everyone points back to. If it changes after production starts, it changes visibly, with a date and a reason.
That last point is where a document starts to strain. A frozen brief in Google Docs doesn't tell you that the SMS is still in draft while the email is in client review, and it doesn't record who approved what. This is where campaign production management picks up, and, for the sign-off itself, campaign approval software. In LaunchSign, an approved brief becomes the campaign itself: the journey laid out across email, SMS, WhatsApp and landing pages, a production status per asset, a review link the client opens without creating an account, and a timestamped record of every approval. It stops at sign-off (your ESP still sends the campaign) but the handoff is a documented, approved campaign rather than a folder and a Slack thread. That whole path, from an approved brief to a signed-off campaign, is what managing a campaign from brief to sign-off walks through.

FAQ
How long should a campaign brief be?
One page. If it runs to three, the detail belongs in linked documents (the copy doc, the segment definition, the legal notes) with the brief pointing to them. The brief's job is to be read in full by everyone who touches the campaign, and a three-page brief isn't.
Who should write the campaign brief?
Whoever owns the campaign outcome: the marketing manager in-house, the account manager at an agency. Not the copywriter and not the designer. They're the audience for it. The person writing it should be able to answer, or chase, every field.
What's the difference between a campaign brief and a creative brief?
A creative brief is about tone, concept, and visual direction for a piece of work. A campaign brief covers the whole send: audience, offer, assets across channels, deadlines per stage, and approvers. On small campaigns they collapse into one document. On multichannel campaigns they shouldn't. The creative brief sits inside the campaign brief as one section.
Do we still need a brief for a recurring newsletter?
A short one, yes, but most of it is a template you copy: segment, sending schedule, approvers, and legal notes stay fixed. Only objective, content, and CTA change per issue. The value of a brief for recurring sends isn't the thinking. It's the approval record.
